Welcome to War and Tactics! War and Tactics Forum is currently undergoing some modifications that might disable features you are used to. This is unabvoidable as we have to update the forum engine to a new structure that is incompatible with many of the features we had used so far. The good news: WaT will be more secure and stable, and most of the features we uninstalled will be a natural part of the new structure anyway. For the rest we will be looking for solutions.

I though I'd post a link to this book here. I really enjoyed a book titled: War of the Aeronauts which tells the story of the development and used of ballooning for recon during the civil war. Something to check out if the topic interests you.
